| The instability produced
if a shock or suddent acceleration takes place is known as Richtmyer-Meshkov (RM) instability. Front advance and mixing is studied analyzing mixedness,[2] the third order structure
functions, that indicate strong inverse cascades towards the large scales producing
spectral variations[3]. The mixing processes are compared by mapping the different intermittency and the multifractal scaling in the spike and bubble arrays
